yeah, mine doesnt have a smell at all except for when I'm cleaning it. when you clean it you get an odor that I like that smells like the beach at low tide.
My pods are going crazy in there but i still don't see the millions of little ones. my sump glass is dirty though so maybe I have to look closer.
SM do you ever have to rerough up the screen? I'm getting a couple of bare spots on mine about the size of a nickle here and there. But I spent about 30 minuts on each side of the screen roughing it up with the hole saw and it looked flawless when i started.

What bulb is the best. My scrubber was working great with the first bulbs i purchased from the site that used to be in this thread. I then purchased bulbs from 1000 bulbs, and my scrubber hardly grows any algae.

Okay SM, now you've got me curious. I've been using the 6500K CFLs and my macro growth was crazy when I first started this process (I did start with a new refuge/sump and display, never had a refuge/sump before). The macro has since nearly stopped growing, of course my trates are only around one now. My scrubber continues to grow its algae at a rate faster than the macro it seems.
If I lower the kelvin as you suggest, what will my benefits be?

Bulb is 1 inch (2.54 cm) from the screen. The bulb is setting on the bottom of the box at an angle, and the screen is also at an angle, and that's the reason that the burned-yellow part is at the bottom, and why the waterline is tilted:
(right click and "view image" to see the whole pic)

I cleaned it today, then sanded the clear window to diffuse the light. The bulb is so near to the screen that you are almost able to see the outline of the bulb in the growth. Scattering the light should help a lot; it's just a matter of how much.
To build this at home, you would just attach vinyl tubing to the pipe, and set the screen down evenly inside the box.
Any updates on whether or not scattering the light helped out? When I was running my scrubber just about all I had was the yellow "burned" algae.

I started out with 23 w 2700 bulbs 1 on each side. not much growth. I now am running a 5500k 27 watt bulb and the results are getting better. I'm going to shorten the screen width/slot width a bit to increase the flow with the same pump. hopefully that helps.

Thanks for the feedback Santa Monica. I am having trouble understanding where i need the additional plastic canvas. I have a piece underneith the pvc pipe attached via zip ties. Maybe this picture isnt the greatest. The acrylic is there as a means of containing any splashing. The light is attached via a strong magnet to the acrylic, shining through to the screen draped from the pvc pipe.
The acyrlic is not what i am using to grow the algea. It is a tray from my old sump (sump converted to a large refugium). I turned the sump tray up on its side. The water comes down from the PVC through a series of small holes over the plastic screen. The water collects on the bottom of the sump tray and out a series of small holes drilled in the bottom of the sump tray into the area with the macro algea.
I'll post a better picture of the unit tonight when i do my cleaning.

yea..picture is from a cell phone and not very good.
its been about 5 weeks with the scrubber now. Still getting mostly black / brown tar like algea. Not getting alot of green algea right now. Cleaning 1 X a week.

Then clean every 3 days until it get lighter brown. then clean every 5 days untl some green. After some green, clean evey 7.
Reducing your feeding by 1/2 will speed up the process.
 
Ok so Im doing the sump version with the screen vertical, SantaMonica do you know if there are reducers that would work with standard wet/dry hoses? My wet/dry hose is about 1" thick. Im sure there are but I was at the hardware store and couldnt find any.

Success updates...
Ddinox44 on the RS site: "I hated the constant drone of my skimmer which aided in the push [to get a scrubber]. I really do see an improvement and I believe my tank is healthier for it. Cleaned my screen today, tons of pods on it. Hurts to wash those critters down the drain after thinking of the money spent trying to stock them."
Docjames on the RS site: "No one in [Taiwan] has ever heard of such a thing, but my mind was determined to either be a success or a failure. At that time, the NO2 and No3 were all off the chart, unmeasureably high. That was 1 week ago. Then this morning, when I did the water check, NO2 was undetectable, NO3 was less than 12.5, PO4 was less than 0.5, Kh was 11 dkh (Sera testing kit), and Ca was 440. So I called up the lfs guy that I planned and purchased everything from, and he told me never in his business (he's had this store for decades) has he ever heard of anything like that. He had insisted that I purchased a good Protein skimmer prior to the start of the aquarium, of which I strongly refused and insisted that I'm going to be a pure ATS only filtration person. Tonight, he brought some fishes, shrimps and invert and they became the first inhabitants of my new aquarium."
Cheely13 on the RS site: "I have been using a alge scrubber for about 6 months now with no skimmer, the only thing i do is use a sock with carbon in it for my corals that i place in new every month i harvest one side every 7 days then the next week do the other side. My tank is very clear and seems to be doing very well. all tests are good. I do a 15 to 20 percent water change every week you know theres nothing like a good old water change."
Schwa on the RS site: "These things work great. I had some brown slimy algae in my display that was not going away no matter what I did so I decided to give a scrubber a shot and within 2 weeks of it running the slimy algae is gone out of my display. I am still running my skimmer and run GFO and carbon in the canister filter that powers my scrubber. My favorite, a tyree flower petal Montipora, has polyp extension that is starting to look like an acro millepora without the white sweeper in the middle. MY stuff is very happy right now the best I have seen in 3 years of reefkeeping. I am a firm believer in the algae scrubber and I think they are soon going to be here to stay for a while."
Amphiprion on the AC site: "Well, an update again. The scrubber is still progressing well. I'm starting to get a predominance of brown turf now, as opposed to the usual green. This stuff is a lot tougher, too. I'm now using a razor blade to scrape the screen, along with a toothbrush to try to get at least some of it off. At the same time, the tank is going through some algal succession as well. The bubble algae has stopped growing, and is now dying, as is much of the tough filamentous algae I had. I am getting a few patches of hair algae, however, I found that they all had one thing in common--they are areas that had deep holes with sand and detritus tended to collect. Extra particles would also settle in the algae itself, further feeding it. So, I scrubbed off the algae and removed it's food source and it has halted growth. The stuff is grasping at whatever it can to keep growing--but not while I'm around. There is a definite noticeable difference from when I started this scrubber. Feeding is at an all time high, while levels of N and P remain minimal to undetectable--PO4 about .01 ppm and NO3 undetectable. I'm feeding about 2 cubes of frozen food daily, plus pellets and coral food mix, which consists of rotifers, cyclops, and phytoplankton. I only have 2 clownfish now and a small handful of corals. I'm basically trying to test the limits of this scrubber and I've yet to stretch it even close to 100 percent."

Jstdv8 on the AC site: "So I tested my water today for nitrates and phosphates and both came back at 0. My phosphates have never been below .5 before. The screen is just starting to grow in and is no where near established like most pics I see of them, yet it seems to be working." Later: "Well, about 5 days ago I cleaned my screen and I added another light to the backside. One of my old 23 watt fully enclosed lights with the reflectors built in.
I also doubled my feeding now that I have a clown in there to help eat some of the stuff I'm dumping in there. The screen is really starting to grow some thick bubbly looking green algae on the side of the screen witht he two lights. The bubbly stuff is growing thickest on the 1" side nearest the 2nd light where there is little flow on the screen because of the tabs where it enters the pipe above (1" tabs on the left and right) both sides of the screen overall are seeing much better growth. Still a little weak, but certainly 10 times better than anything I've been seeing up until now. I'm going to play around with it and see if I can still get the same growth without the second light and continue the heavy feeding (also adding a much larger CUC) or if the second light is the hot ticket. I'm hoping to not have to use the second light as it's just more power consumption, but I'll see how it goes. If it truely needs more light I might build up something like SM's T-5 setup instead. I'm getting the zillions of miniture pods all over my front glass in my DT now. I have a mandarin and a sixline and will not hesitate to add more pod eating creatures in the future as there is way more than enough for everyone. phosphate and nitrate are still showing zero. Still have two large patches of GHA in the DT, but now that the screen is starting to grow faster I think I'll remove as much as I can during the next water change and hopefully get the screen to finally outcompete for the nutrients."
Kdc on the MD site: "built a scrubber for myself some time back. All i have to say is awesome! I have yet to see something that compares to it. it has literally taken all the work out of keeping marine fish. My nitrate level is zero, i have never seen that before, even using phosphate absorbers and skimmers. which are very expensive, and always missing with them. if anybody is skeptical dont be, this thing works and works very well."
Borge on the MD site: "don't remember how long ago I started my ATS, I've had some bad *** yellow algae (not diatoms or some easy to get a hand on algae) that grew on anything, and a heavy duty deltec 902 and ozone figthing a constant battle on those food particles, and loosing bigtime to this algae. of course its still there, but shrinking. BIGTIME. don't know any po4 numbers (seriously I hate testing for anything other than whats available at the LFS). What I do know is zero on the no3 (witch is ok considering all the algae) but no silicates and I didn't supply my tank with some new sand full of silicates! anyway today I found blank spots on my ats 6 or 7 days since last cleaning and pods ate greedy on my rug screen. now, base color on this thing is yellow for the algae, but don't you know it, it's turning green, as in long green hair, and coralline is showing up everywhere in the sump, together with a larger amount of baby snails and macros is growing... BIGTIME. Now I feel like I'm fighting a winning battle. oh... btw... my skimmer has been off for as long as the ats has been on... nothing is dying, everything looks more healthy than it's been for a 5 months. I feed just as much if not more, the fish hunts more and my banded goby is always out of his hole picking at things in the water column."
Allnatural on the MD site: "well my tank has been up for 6 weeks now. i used my ats from the very beginning. i had a very short cycle and only a small diatom bloom in my dt. it took a while for my screen to start but now it is turning green and i clean it weekly. i have yet to add any fish or corals but i did add a small cuc consisting of 3 turbo snails, 3 astrea snails and 4 nassarius snails. after the 3rd week my water parameters have been and consistantly remain perfect. nh3=0 no2=0 no3=0 po4=0 ph=8.4 cal=420 alk=13.4. i am adding my first corals this weekend. i thought i wouold see the usual algea bloom that most tanks get after the first month of operation but have yet to see any other then the initial diatoms. my copepod population is extreme and coraline is now covering my aragrocrete rocks i made. my live rock is still as healthy as the day i bought it. im so excited this tank is going to be sweet!!!!!"
